CAR SEAT.

Application filed April 11, 1927. Serial No. 182,750.

This invention relates to an improved car seat, and more particularly to a car seat which can be reversed so that the occupant may face in either oftwo directions, the seat comprising a back, a seat-cushion, and a foot-rest, and means for supportmg the different parts whereby they will move in unison from one position to the other.

More specifically, the car seat comprises a .tixed'frame and a seat-cushion carried by rockers slidable laterally across the frame whereby the lateral position and inclination of the cushion may be changed. lhe'back s supported on the frame by means of a pa r of parallel links, and a lever or levers positioned intermediate the links and connected with'the back and with one of the cushionsupporting rockers serve to shift the cushion in unison with the back, but iii an opposite direction. The foot-rest is supported upon levers pivoted in the frame, one or more of the levers beingconnected with the cushion; supporting'rockers so that the foot rest will also be swung from one pOSIiBIGIL to another in unison with the movements-of the back and seatcushion. .7 j

The main object of the invention is to provide an improved car seat of the type briefly described hereinabove and described in more detail in the description which follows.

Other objects and advantages of the invention will be more apparent fromthe following detailed description of one approved form of car seat involving the principles of this invention. I i

Fig. 3 is a transverse vertical section, showing the parts illustrated in Fig. 2, this view being taken substantially as if looking from the right at Fig. 2. y i y Fig. 4 is a plan view ofthesupporting and operating mechanism, the back and seat cushion being removed. v

Fig. 5 is a partial horizontal section taken substantially on a line corresponding to the line 5-5 of Fig. 3, but through the opposite or aisle end of the car seat, instead of the car-wall end shown in Figs. 2 and 3,

back so that it is reversible.

back frame is concealed by the upholstery,

dicated at 25.

Fig. 6 is a perspective view of oneof the rockers. l

The supporting frame comprises apair of spaced, parallel, horizontally extending sills 1 and 2, preferably formed of angle-iron sections, these sills being attached at their ends to angle plates 8 which in turnare bolted or riveted, as at 4:, to the similar p'ressed metal end plates 5. The end plates 5 are provided with edge reinforcing flanges 6, andgthe intermediate portions of the plates areipressed inwardly, as at Y and8, to provide clearance for the heads of the bolts, rivets andshaft bearings mounted in the end plates. The

end portions of the sills 1 and 2 may be supported on suitable pedestals 9, or as in the example here shown, one end of the frame may be supported on a pedestal 9 and the other end supported by attacl'iing the end plate 5 in any. suitable manner tothe wall 10 of the car. This endplate 5 may rest upon a plate or ledgell formed onthe car wall. Suitable arm rests 12 and end coverplates 13 may be attached to and supported by either or both of the end plates 5,in amanner hereinafter described.

The back 14 comprises cushions lemounted on a suitable supportingframe, the cushions being duplicated at both sides of the Most of the but outer pocket members 16 are provided along the lower part of each end edge of the back, these pocketslo being adaptedto .removably receive the upwardly projectingends 17 of the back arms 18. The armsl'f' are secured by. screws or 111 any other shit able manner within the pocketmembersld The back arms comprise the lower, substan tially triangular plates 18, to the upper ends of which the upwardly extending arms 17 are joined bythe inwardly extending arms 19. Two similar supportinglinks 20 and 2l, arranged substantially parallel with one another, are pivoted or hinged at their upper ends 29 to the plate 18, and arehinged at their lower ends to the inwardly pressed portion 8 of the end plate 5. Bolts or rivets .23' have their reduced ends 2t passed through the end plate .5 and then riveted down and spotev-elded to the plate-5, as in- The lowerv ends of the links 20 and 21 arepivoted on thereducedinner ends 526 of rivets 23, and are held thereon Ill hr the nuts 26. Similar means may he used for pivoting the upper ends of the limbs 20 and 21 to the plate 18. This form of pivotal connection is merely illustrative, and other means might he used for pivoting the links 20 and 21 to the end plate 5 and llil-tll11l plate 18. lVhen the hack 1-.l-. is swung to one position. lor example to the left, as shown in the drawings. the link 21 will engage and rest upon a. ledge or seat 27 formed on the sill and thus limit the swinging movement ol the hack and support this end ol. the hack. The same mechanism is duplicated at the other end of the hack and frame. hen the hack is swung over to the right to its opposite position it will he supported by the engagement of link with a seat 28 formed on sill 1.

The seat cushion 2S) supported upon a pair ol similar rockers ill). These roel-zers are substantially identical in eonstructic'm, one of them being illustrated in perspective in Fig. 6. Each rocker comprises a vertical well 31, which is cut away centrall' at 32 to clear the rock shaft 50. hereinafter described, the web 31 supporting a plurality of plates 33, all positioned in the same substantially horizontal plane for supporting the cushion 29. Studs 3i projecting upwardly from certain of the Sll1)1')01'tll1 plates 33 may engage suitable sockets in the frame of cushion 29 to anchor the cushion in place. l he lower portion of the rocker comprises sidewardl extending}; ribs or flanges 35 and 36 which incline downwardly from the ends of the rocker toward the center thereof. The flanges 3:") are adapted to slide upon and he sup 'iorted h the sill l, and the flanges 36 are correspondingly sup ported by the sill The sills are termed with seats or Sll(lG\\'21}'S for the rockers, the seats comprising lingers $37 which n'ojeet over the :llannes 35 and 36 to hold the rockers slidahly in place upon the sills. It will be apparent that when the rockers are slid transversely across the sills 1 and 2 to one limit of theirmoven'ient. as illustrated in Figs. 3 and l. the cushion 29 will be projeeted somewhat toward the right as seen in Fig. 1. and will. he inclined downwardly toward the left or toward the seal-hack 14, this heing lhe desirahle position of the oushion. both for the comfort of the occupant and for the economy ol space within the \Vhen the hack is swung to ils other position. that is toward the, right in Fig. 1, it is desirahle that the cushii'm 99 he projected toward the leilit and inclined downwardly toward the right. l\.[echanism provided for accomplishing the simultaneous shifting of the hack and cushion between their different respective positions. The rock-shaft 50, previously referred to, is pivotally supported at its ends, preferablyhy means of bearings resireii 8S pressed in place within the end plates 5, as shown in Fig. Lovers 39 have hulls 40 at their lower ends secured on the respective ends of rock shaft adiarent the end plates Pins 41 may he passed through the lllllJS l0 and shaft 50 to fix the lovers Ilcil1l(lt:llilllll}' to the rock-shalt. llaeh lever 'll) rarries at its upper end a pin or stud al which engages rotatahly within an opening lil in the plate i8 01' the hack-arm. Prelerahl v the opening 4:3 is elongated and provided wilh a larger upper end ell; as indicated in Fig. fl to permit the ready detachment of lever Zlll lrom plal 18. It will he noted that the l ver arm 39 is positioned midway hetweeu the linli's i l and :21. and moves parallel therewilh at all limes Levers secured at their upper ends to rock-shaft 50. for example hy pins ill passed through the levers: and sha ll are pro vided at their lower ends with inwardly projiectin; studs 4-7 which engage sliiilahly with in vertic: l cam slots il-8 formed at one side of the central portion ol rockers fill. it will he evident that as the hacl; it is SWIHLSI from one position to another. the levers I share the swinging movement oi the links "ill and 21. and the lower levers 45 will swing in the opposite direction 'lriuu the nu'wernenl of levers 35] and the hack ll.
